Synopsis
========

Some applications shipped with MIT Kerberos 5 are vulnerable to local
privilege escalation.

Background
==========

MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol. It is designed to provide strong authentication for
client/server applications by using secret-key cryptography.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-crypt/mit-krb5 < 1.4.3-r3 >= 1.4.3-r3

Description
===========

Unchecked calls to setuid() in krshd and v4rcp, as well as unchecked
calls to seteuid() in kftpd and in ksu, have been found in the MIT
Kerberos 5 program suite and may lead to a local root privilege
escalation.

Impact
======

A local attacker could exploit this vulnerability to execute arbitrary
code with elevated privileges.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MIT Kerberos 5 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=app-crypt/mit-krb5-1.4.3-r3"
